IMPROVEMENT IN APPARATUS FOR COATING METAL PLATES.

Specification forming part of Letters Patent No. l 7 1,688, datedJanuary 4, 1876; application filed December 6, 1875.

CASE B.

-To all whom it may concern:

Be it known that We, EDMUND MOREWOOD, of Llanelly, and JOHN HENRYROGERS, of Llangenneoh Park, near Llanelly, both in the county ofGarmarthen, Great Britain, have invented an Improvement in CoatingMetals; and the following is declared to be a full and correctdescription of the same.

Our invention relates to means for righting or putting into propercondition the oil, grease, or fatty matter which has become frothy orporous, and thereby unsuitable, and which is especially used inthe'process of coating plates or other pieces of iron with tin or terne,such plates being coated with such oil, grease, or fatty matters inorder that they may more readily receive the subsequent coating withFigs. 1 and 2, which rises higher than the box a; and there is a spacebetween the two extending all around, as in Fig. 2, or at three sidesonly, as in Fig. 3. d are holes in the lower part of the box at, openinginto the vessel b. The Wet black clean plates are introduced into theinner box or vessel a,between the pins 0, in order to be heated andgreased by the flux contained therein preparatory to coating metal.

their being passed into the bath of melted The froth arising from theboiling grease flows over the top h of the inner vessel on into theouter or overflow cistern b, and, after righting itself and becomingmore heavy and solid, flows back through the holes d-into the innervessel a, provided the column of solid grease in the settling device isheavier than the column of frothy grease in the fluxbox. In the verticalsection, Fig. 4. the vessels a and 1), instead of being 'one within theother, are placed side by side and connected at top and bottom by pipesh d. The operation is precisely the same as that before described, thefrothy and porous grease overflowing, by the pipe h, into the vessel 12,where it rights itself and re-enters the vessel 11, by the pipe 01, in amore solid and non-frothy condition or the frothy grease might overflowinto alarge gutter or pipe of anysuitable size and form, instead of aspecial settling-vessel.

We do not claim asettling-vessel, b, in combination with mechanicalmeans or appliances for producing an artificial circulation of thefluid; but

We claim as our invention- The flux-pot a, overflow h, settling-vesselI). or equivalent device, and return-opening d, so

'as to produce an automatic circulation of the flux, substantially asand for the purposes set forth.
